To all whom it may concern:

Be it known that l, Bonner 'WHITE, 21 citizen of the United States,residing at Beaver county of Beaver and State of Pennsylvania, haveinvented certain new and useful improvements in Valves for Gas- Engines;and I do hereby declare the following to he a full, clear, and exactdescrip tion of the invention such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to the regulating valves of gas and gs-solencengines; and it consists in the novel construction and co1nloinetion ofthe parts as hereinafter fully describedvand claimed. v

in thedrawings, Figure l is a vertical section-of a portion of an enginepro videdwith e rotary valve according to this inven view of a portionof the engine cylinder and the valve casin Fig. 8 is a plan view of thevalve support. Fig. l is a side view of the valve showing it at thecommencement of the intake stroke. Figs. 5, 6 and T, are cros lionstaken on the lines 5 -5. 6-45, and 1- in showing the relative positionsoi the po at the comniencen'xci'it oi the intake In Fig. lthe parts areshown in th tions at a part of the exhaust stroke.

A is a portion of the power cylinder oi a. gas or gasolene engine,.snd Bis a portion of its Water-jacket.

C is the casing of the regulating valve,

upper end portion or" the cylinder. The valve-chamber of the c: isconical in form and its larger end is arranged uppermost.

D is a cap or cover which closes the larger end of the valve-chamber,and d is a bearing r01- tlie valve-spindle arranged on the valve-chamberand at the lower end thereof.

E is the inlet port and l is the outlet port of the vnlve-chamberz'llicse ports are arranged at diil'erent levels from the port 0, andfrom each other, and at the opposite side'of the valve-casin from. theport 0, and the outlet port T! is arranged lE lUl/Q the inlet port evalve which is conical in fol-Tn, o is gournaleo in the valve-cs" o asto revolve freely. The valve G. is

hollow and it has a conical bottom portion g, and s driving-spindle 7L.spindle 71 is journaled'in the bearing d, and it projects at the lowercasing.

The drivingend of the valve- 1 is the driving-shaft supported in anyapproved hearings eled toothed for revolving and provided with abevwheel 1t continuously.

J is a coupling provided with a tapered pin j of soft metal whichconnects the shaft 1 with the valvespindle it, and which pin is shearedofl whenever the valve sticks or seizes in its done.
